Advice from

Power tool battery buying guide

Power tool batteries work using lithium-ion, nickel cadmium or nickel metal hydride technology. But all types of battery differ in terms of voltage (12, 14.4 or 18V) and capacity (1.2 or 3 Ah) which dictate the strength and life of your battery. Read on to find the right type of battery for your cordless power tool!
